SplitBlockPredecessors is unable to insert an additional BasicBlock between an indirectbr/callbr terminator and the successor blocks. This is needed by Polly to normalize the control flow before emitting its optimzed code. This patches rejects regions entered by an indirectbr/callbr to not fail later at code generation. This fixes llvm.org/PR51964 |

Polly - Polyhedral optimizations for LLVM ----------------------------------------- http://polly.llvm.org/ Polly uses a mathematical representation, the polyhedral model, to represent and transform loops and other control flow structures. Using an abstract representation it is possible to reason about transformations in a more general way and to use highly optimized linear programming libraries to figure out the optimal loop structure. These transformations can be used to do constant propagation through arrays, remove dead loop iterations, optimize loops for cache locality, optimize arrays, apply advanced automatic parallelization, drive vectorization, or they can be used to do software pipelining.
